Study of Process Parameters in High Pressure Die Casting

A study has been carried out for the die casting process parameters in order to achieve the improved quality of high pressure die casting (HPDC) products, which is the challenge for the small and large scale manufacturers of HPDC products. Aluminum - Silicon alloys are the most extensively used, Aluminium alloys are widely used in high - pressure die casting (HPDC) of automotive components. Several process parameters need to be controlled during HPDC in order to obtain sound and reliable castings. . The objective was to reduce the defects in the components to obtain the good quality castings and increase productivity. The porosity is the most common defect frequently encountered in aluminium high pressure die castings, which increases the rejection rate and scrap rate and reduces the productivity. Porosity formation is closely related to die casting process. In this paper the effect of process parameters on porosity formation in HPDC have been presented.
